The rulebook has been thrown away: re-imagine the ultimate XC race bike and join the revolution - where up meets down. Born to surpass the demands of the world’s top XC athletes, the Fourstroke 01 delivers the ultimate performance on the most demanding courses. A purpose-designed race machine, every element of its structure is crafted to optimize speed, save seconds, and keep riders ahead of the pack. BMC's all-new Race Application Dropper Seatpost (RAD) ensures that its fast and smooth adjustments maximize power and control whatever the gradient, allowing you to ride more dynamically. The revised Big Wheel Concept Race (BWC) geometry has evolved to embody the progressive riding style our athletes display on technical World Cup tracks. The Fourstroke 01 shifts the paradigm. Reel in the competition on the climbs, drop them on the descents. Every second matters.

For a full-suspension XC race bike fully prepared to take on the world circuit, look no further than the Fourstroke 01 ONE. The carbon front and rear triangles add stiffness and keep frame weight low, while the Advanced Pivot System delivers pedaling efficiency, traction, and control. A Fox Float fork and rear shock provide 100mm of travel for today's technical XC courses and feature Kashima coatings and remote lockout capabilities. SRAM's XX1 Eagle drivetrain includes a super-wide 10-50 cassette, while SRAM Level Ultimate brakes deliver unmatched stopping power. This bike's race pedigree is taken even further with DT Swiss XRC 1200 wheels - the added stiffness of boost hubs is paired with carbon rims that respond to the rider's power with super-fast spinup. A Fizik Antares R5 saddle sits atop the integrated RAD dropper seatpost; an innovative design that provides 80mm of travel. BMC's holistic approach to this bike's design resulted in their fastest and most intuitive race bike ever.
